Limitation extension under VAT savings clauses is limited; post-repeal amendment beyond legislative competence is unconstitutional.

The amended third proviso to Section 25(1) of the Kerala Value Added Tax Act was construed to validly extend reopening only for assessments whose five-year limitation would otherwise have expired by 31 March 2017, so those cases could be reopened up to 31 March 2018. However, once the GST regime had come into force and the KVAT Act had been repealed, the State Legislature lacked competence to further amend the repealed statute. The Kerala Finance Act, 2018 could not rely on the saving provision to extend reopening to 31 March 2019 or beyond, and that amendment was therefore unconstitutional.

Issues: (i) Whether the amended third proviso to Section 25(1) of the Kerala Value Added Tax Act could be used to reopen assessments whose five-year limitation had expired by 31 March 2017; (ii) Whether the Kerala Finance Act, 2018 could validly further extend the reopening period after the constitutional change and repeal of the VAT regime.

Issue (i): Whether the amended third proviso to Section 25(1) of the Kerala Value Added Tax Act could be used to reopen assessments whose five-year limitation had expired by 31 March 2017?

Analysis: The main amendment enlarging the reopening period from five years to six years operated prospectively from 1 April 2017, but the third proviso was designed to save assessments whose limitation was about to expire by 31 March 2017. A proviso may qualify the main enactment and, where the legislative intent is clear, may operate to explain the intended reach of the provision. On that construction, the proviso gave effect to the extension for the limited class of assessments that would otherwise have become time-barred by 31 March 2017.

Conclusion: Yes. The assessment years whose reopening period expired by 31 March 2017 could be reopened up to 31 March 2018 under the 2017 amendment, in favour of the Revenue and against the assessee on this issue.

Issue (ii): Whether the Kerala Finance Act, 2018 could validly further extend the reopening period after the constitutional change and repeal of the VAT regime?

Analysis: After the constitutional shift to GST, the State Legislature stood denuded of power to continue unilateral legislation on sale or purchase tax except to the extent constitutionally retained. Once the KVAT Act had been repealed and the new GST regime had come into force, the savings provision could preserve accrued rights and pending actions under the repealed law as it then stood, but it could not authorise a further amendment of the repealed enactment. A saving clause is distinct from a post-repeal legislative amendment, and the latter was beyond legislative competence.

Conclusion: No. The 2018 amendment was invalid and unconstitutional insofar as it purported to extend reopening to 31 March 2019 or beyond.

Final Conclusion: The 2017 amendment was sustained to the limited extent of reopening assessments that would otherwise have become time-barred by 31 March 2017, but the 2018 amendment was struck down for want of legislative competence after the GST constitutional change and repeal of the KVAT Act.

Ratio Decidendi: A proviso may validly give limited retrospective effect to a limitation extension where legislative intent is clear, but once the parent fiscal statute is repealed and the legislature has lost competence over the subject matter, it cannot further amend the repealed enactment except through a constitutionally authorised savings mechanism.
